TlE-PLATEi useful Improvements in Tie-Plates of which the following is aspecification.

This invention relates to that class of tieplates having a grooved orribbed upper face and provided with ribs on its under side extending atan angle with relation to the upper ribs or transversely of the platefor preventing the plate and thereby the rail supported thereon fromslipping or moving longitudinally upon the tie.

Theprincipal object of the invention is to provide a simple, economicaland efficient tie-plate.

A furtherobject is to provide a tieplate of minimum weight and maximumstrength and provided with integral depending or bottom rib ortionsadapted to prevent the longitudina movement or slipping of the plateuponuthe tie andfqrm' substantially theload bearin bottom surfaceportion of the plate beneat the rail,the. top ribs bein adapted tostrengthen the plate longitudinally, whereby. longitudinaldependingflanges may be dispensed with and the desired adhesion or security ofconnection with the tie afforded without unnecessarily cutting into orinjuring the fibers thereof.

A further object is to provide a tie-plate formed of rolled metal,having a grooved or ribbed upper face and bottom load-supporting andrail retaining ribsso formed that the load is evenly distributed uponthe bottom surface portion of the plate formed by such ribs, such ribsforming substantially the entire load supporting bottomsurface of theplate, and the top and bottom ribs being so constructed and arrangedthat plates of various widths and each having the same top cordance'withmy, improvements, showing Specification of Letters Patent.

the bottom diagonal ribs in broken lines eX tending at an angle withrelation to the top' ribs; Fig. 2, a longitudinal sectional view inelevation taken on line 2 of Fig. 1, looking in the direction of thearrow, and Fig. 3,; a transverse sectional viewin elevation taken online 3 of Fig. 1 looking in the direction of the arrow, or toward therail retaining shoulder.

In constructing a tie-plate in accordance with my improvements I providea main body portion a formed pre'lerablyofrolled metal and of sullicientlength to extend beneath and transversely beyond the sides of a trackrail to be mounted thereon, so as to form a support for such rail andprotect the tie. Each plate is provided with perforations b and carranged at suitable intervals and preferably in such position thatthose on the outer side of the rail are in staggered relation to thoseon the inner side. A rail retaining shoulder (l extends transverselyacross the upper side of the plate in position to en age the outer edgeof the flange of the rail w en in position. The outer spike holes 0 mayextend through the rail retaining shoulder and are reinforced thereby.The. upper side of the plate is provided with a series of ribs (1 whichextend from the inner end of the plate to the transverse rail retainingshoulder or diagonally upon the upper side of the plate. These ribsextend transversely with relation to the rail and longitudinally of theplate to such an extent as to aflord the re uired lon itudinal rigidity,and thus enab e longitudinally extending bottom flanges which would cutdeeply into the libers of the tie to be dispensed with. Said ribs arealso at an oblique angle with relation to the bin gitudinal center orlength of the plate, so that they give the plate an amount of transverserigidity which is very desirable. Bottom ribs fupon thc under side ofthe plate extend diagonalily across the plate and at an angle--preferably almost or quite at right .angle's with relation to the upperribs, as indicated in broken lines in Fig. l. 'lhe thus supplement theupper ribs in strengthening the this be accomplished in such a manner asto enable flanges which sink deeply into the tie to bedispensed with.The bottom ribs are therefore made of reater width than depth,

7 each forming a slig tly inclined load-bearing bottom surface portion 9and having a pref-- erably upright side face i on the side toward theouter end of the plate of only sufficient depth to prevent the plate,when properly mounted and secured to the tie, from movnn longitudinallyand give the ribs the require strength. The slightly inclined bottomface of each bottom rib extends preferably from the outer edge orupright side of such rib to the outer upri ht side of the next adjacentrib and toward the inner end of the plate so thatthe entire load bearingbottom face of the plate beneath the rail is formed by said bottom ribs,the same being so constructed that the weight of the load is evenlydistributed over-.every part of the bottom surface formed by said bottomribs. Ailat bottom surface portion 'i may be provided at either or bothends of the plate on the outside of the ribbed portion, or laterallybeyond the sides of the rail 7:.

The tie-plate thus formed is adapted to be rolled efficiently andeconomically, and any desired number of plates of unequal or variouswidths may be rolled by the same rolls and yet have the same top andbottom contour, configuration or arrangement of ribs, and. the requiredstrength in proportion to the Width of each plate respectlvely.

I claim: v

1. A tie-plate having on its upper side a series of ribs, and having onits under side a series of retaining ribs extending at an angle withrelation to the upper ribs.

A tie-plate having on its upper side a series ,of ribs extendinglengthwise of the plate at an oblique angle with relation to itslongitudinal center, and having on its under side a series of ribsextending at an angle with relation to such upper ribs.

3. A tie-plate having on its upper side a series of ribs, and having onits'under side a series of retaining ribs extending obliquely withrelation to such upper ribs.

.4. tie-plate provided with spike holes therethrough and having on itsupper side a series of ribs extending dbliqu'ely of the plate betweenthe spike holes, and on its underside a senes of ribs extendingobliquely with rclation to such upper ribs.

'5. A- tie-plate having on its u'pper side a transverse. shoulder and aseries of 'ribs eX- tending obliquely with rel a ionto such sh oulder,and having on its under sidea series of ribs extending at an angle withrelation to the upper ribs. I

6. A tie-plate'provided with spikeholes therethrough and having on itsupper side a transverse shoulder and a series of-llpper-ribs extendingat an angle with relation to such shoulder, an d. having on its underside a series of retaining ribs extending at an angle with relation tothe up erribs. V

7. A tie-plate raving on its under side a series of retaining ribsextending obliquely of the plate and each having an upright side face inthe direction of one end of the plate and a bottom surface portionextending upward and at an incline in the direction of the opposite endof the plate.

8. A tie-plate having ribs on its upper side,

and provided with a series of retaining ribs vided on its under sidewith a series of retain- I00 ing ribs extending at an angle withrelation to the upper Ill)S and each having an menned bottom surfaceportion and an upright side face.

1]. A tie-plate having spike holes there- 155 through, and provided witha seriespf ribs on its upper side, and having on its under side a seriesof ribs the bottom surface portions of which-form the entire loailbearing bottom surface portion of the plate between 110 the spike.holes.
